Request to active interpreter returns Uris with different casings for the same environment

[DonJayamanne]

When calling the API method to get the active interpreter we get the same environment, however sometimes the Uri (path to the executable is lower cased and sometimes its upper cased)

This causes issues in the Jupyter extension as the Uris are different values
Suggestion: Is it possible for Python to cache the Uri per Python Env Id, so that this never changes.

Wasn't able to reproduce this on Windows, we only norm case "id":

Could it be that Jupyter is manipulating Uris again on their end?

[DonJayamanne]

@karrtikr not sure what more information you need from my end here.
I've transferred the issue here microsoft/vscode-jupyter#12487
You can see from the logs that the parts are in upper case

Are you can see in the logs some are upper case and some are lower case. See here microsoft/vscode-jupyter#12487

not sure what more information you need from my end here.

Just wanted to confirm it's the Python API which is returning this and not Jupyter, as I wasn't able to repro it.

[karrtikr]

Jupyter is still passing id to resolveEnvironment which is the cause of this issue, I remember bringing this earlier as well that this scenario is not supported, looks like it isn't fixed:

@karrtikr thanks, lets close this issue then.
I'll fix the code at our end.
